The bushes are vigorous, with a growing season of 152–160 days. Clusters are large, cylindroconical, often branched and relatively loose, with an average weight of about 600 g, sometimes up to 2 kg. Berries are very large, oval or egg-shaped, yellowish-amber in color with a dense waxy bloom. The pulp is fleshy and possesses a pronounced muscat-citron aroma.
The variety has moderate resistance to downy mildew and rot, but high resistance to powdery mildew. Frost resistance is about -18°C; it requires covering and a sum of active temperatures of at least 3200–3300°C. Bud fruitfulness is relatively low, and the berry skin is firm, which ensures high transportability and suitability for storage.
